Use the Tool that Works Best
“… the other choice—which I feel corresponds more nearly to the way chosen by Lévi-Strauss—consists in conserving in the field of empirical discovery all these old concepts, while at the time exposing here and there their limits, treating them as tools which can still be of use. No longer is any truth-value attributed to them; there is a readiness to abandon them if necessary if other instruments should appear more useful” (Derrida 357).

"Thus it has always been thought that the center, which is by definition unique, constituted that very thing within a structure which governs the structure, while escaping structurality. This is why classical thought concerning structure could say that the center is, paradoxically, within the structure and outside it. The center is at the center of the totality, and yet, since the center does not belong to the totality (is not part of the totality), the totality has its center elsewhere.The center is not the center" (Derrida 354).
